I'm planning on getting 5x114.3 wheels and ive heard it will put some stress on the wheel studs and probably crack them, so would it be a good idea to get 4 adapters 5x115 to 5x114.3? Or am I good without them?

Photoshopped Booyaka's old setup to black, which looks better on a white challenger? Polished lips or full black??

You'll be fine without. There's lots of people that have run them without any problems. To get an adapter you're going to have your wheels spaced out too far.
True but the XXR ones are +30mm all around which is a higher offset than my current ones. So that's why I thought I might need spacers?

These guys are performance experts on these cars, if they say don’t do it I would certainly respect their judgement.

I've heard from people on both sides. Some would never put 114.3 wheels on a 115 car, but others have run them like that for years without any issues. I was going to do it at one point, but decided against it. I just didn't want to risk it with my family in the car.

In the end, it's up to you. Personally, I wouldn't do it. There are lots of 115 wheel out there to choose from nowadays.

I can live with some minor spacers (have 5mm hub-centric spacers on my Impala), but not sure i'd want to use adapters...

Yeah totally understand, I have my wife in my car at times and wouldnt want to risk it either. Anyways, my money is on the demons but they dont weight that much more than the OEM hellcats i have now. I also prefer the look of the HR5 (hell raiser) wheels but not sure if any replicas out there of them?

Straight from the Maximum Motorsports website:

Are wheel spacers safe?

Yes. When properly installed they are just as safe as wheels installed without spacers.

Will wheel spacers cause my wheel studs to bend?

No. The load from a wheel is transferred to the axle/hub through the friction of the clamped joint, not through the wheel stud. A wheel stud can only bend if the lug nuts are not properly torqued, in which case the wheel is about to fall off, anyway.

The Physics of Keeping the Wheels On

As long as the wheel, hub, and spacer are stiff enough to prevent flexing and loss of clamp force, the cause of most wheel stud failures is under tightened lug nuts (not enough clamping force) or over tightened lug nuts (the stud has been stretched past it's elastic limit, so the clamping force goes away). Therefore, properly installed wheel spacers are perfectly safe.
The wheel stud applies a clamping force that holds the wheel to the hub. When the lug nuts are tightened, the wheel studs stretch elastically, like very stiff springs. The lug nuts should be tightened until the stud is at 90% of its elastic limit. This will provide the greatest possible force to hold the wheel to the hub.
The amount of clamping force at a joint is important because of the coefficient of friction (Cf). The more clamping force applied to the joint (in this case the joint between the wheel and the hub), the more force required to make the wheel slip relative to the hub. Unless the wheel slips on the hub, there cannot be any bending load on the stud.
Coefficient of friction -- There is friction between the wheel face and hub face. This friction can be measured, and it is called the "coefficient of friction". The coefficient of friction (Cf) is the ratio of normal force, at the intersection of two surfaces, to the lateral force required to slip the bodies relative to one another. As an example, good street tires have a Cf of 0.9. This means that if there is a 100-pound vertical force applied to the tire, the tire can generate 90 lbs. of cornering force before it slides.
When the car starts moving, the stress applied to the stud does not change appreciably, unless one of two things happens:
The vertical component of any external force applied to the wheel is so great that the clamping force is not sufficient to hold the wheel in place, and it slips on the hub. At this point the stud is loaded in bending and in shear, and may yield, or even break.
Some portion of the clamped joint, wheel, or hub is not stiff enough to prevent flexing, and allows the tension load on the stud to drop to zero. With no tension load on the stud, the clamped joint is no longer tight. The wheel can then move relative to the hub, and place a bending load on the studs.
Inserting a wheel spacer between the hub and wheel changes nothing about these physics.
The hub center of a hubcentric spacer does not hold the spacer on the hub or reduce the chance of stud failure. There is never any load on the lip of the wheel spacer. For there to be a load on the lip, the friction force in the joint must have been completely overcome. The lip on a hubcentric wheel spacer serves only as an aid for wheel installation.
Increasing the length of the wheel studs to use a wider wheel spacer has no appreciable effect.

I understand the struggle

There are a lot of wheel options we are missing out on because of that minimal difference.

Imo if you find a set of wheels you like, and happen to be 114.3 not x115 i would just bore out one of the lug holes. Then you eliminate the need for spacers but also may render the wheel unsellable

i got a 114.3 spare that i had in a ford of mine when i got new wheels for it. so used one of the old wheels as spare in ford & ford spare in my challenger so could have actual spare but would not do it on a regular basis.

They may be more an animal all their own rather than a replica, but they bear more of a resemblance to the Hellcat 5 spoke (SRT) wheels than the Demon wheels

I like chrome on wheels. I like yours better with the chrome. But don't go by me, I'm apparently very old school........and old.

I'm with you there.... I've never been a fan of black wheels - one of the reasons I can't wait to replace the stock 19" wheels on my 2018 GT - I'm going to use stock Challenger 18" 5-spoke wheels with chrome wheel skins.

I put Dodge Charger wheels on my 2012 Impala and used chrome wheel skins - I love those things. If they ever get damaged (curb rash, etc), you can replace them all for about $80 and have a set of brand-new looking wheels again! :)

They also have black wheel skins for a lot of wheels too - so you can choose between black or chrome....
